Petra Diamonds Limited - Further update in relation to Petra Diamonds UK Treasury Limited

· Issued by Petra Diamonds Limited via PR Newswire

Summary by 6ix AI

At a hearing on October 14, 2026, a court made a winding-up order (an order to close down and liquidate a company) against Petra Diamonds UK Treasury Limited, a wholly owned, indirect subsidiary of Petra Diamonds Limited, a diamond miner with interests in two underground mines in South Africa.

Key details

  • The order followed a winding-up petition from HM Revenue & Customs (HMRC), the UK tax authority, advertised in the London Gazette and first disclosed by Petra Diamonds on October 2, 2026. It covers £5,647,811.32 of corporation tax for the year ended June 30, 2025.
  • The tax arose on interest income accrued on a receivable due from Ealing Management Services (Proprietary) Limited, another indirectly, wholly owned Petra subsidiary. The subsidiary had not received the accrued interest from its affiliate.
  • Both Petra Diamonds UK Treasury Limited and Ealing Management Services (Proprietary) Limited are non-operating subsidiaries and do not own or operate any of Petra's mining operations. Petra says the petition relates solely to Petra Diamonds UK Treasury Limited and does not directly affect the group's mining operations.

What’s still pending

  • Petra Diamonds is assessing what the petition means for the group's financing arrangements and ongoing refinancing discussions, and says it will give further updates when appropriate.

(the "Company")

Further update in relation to Petra Diamonds UK Treasury Limited

On 2 October 2026, the Company announced that a winding-up petition in respect
of Petra Diamonds UK Treasury Limited ("PDUK Treasury"), a wholly owned,
indirect subsidiary of the Company, had been advertised in the London Gazette by
HM Revenue & Customs ("HMRC") (the "Petition") in respect of £5,647,811.32 for
the year ended 30 June 2025, due to HMRC in relation to corporation tax. This
arose in respect of interest income accrued on a receivable due from Ealing
Management Services (Proprietary) Limited, another indirectly, wholly owned
subsidiary of the Company and affiliate of PDUK Treasury. This liability to tax
arose notwithstanding that the accrued interest was not and has not been
received by PDUK Treasury from its affiliate. Both PDUK Treasury and Ealing
Management Services (Proprietary) Limited are non-operating subsidiaries of the
Company and do not own or operate any of Petra's mining operations.

At the hearing of the Petition today, the court made a winding-up order in
respect of PDUK Treasury. The Petition relates solely to PDUK Treasury and does
not directly affect the Group's mining operations. The Company is assessing the
implications of the Petition for the Group's financing arrangements and ongoing
refinancing discussions. Further updates will be provided as and when
appropriate.

The person responsible for releasing this announcement is Tumi Dakada, Acting
General Counsel and Company Secretary of the Company.
